SGM5348-12

8 Channels, 12-Bit Digital-to-Analog Converter

with Output Operational Amplifier

GENERAL DESCRIPTION

FEATURES

The SGM5348-12 features 8 channels of digital-to-

analog converter (DAC) with output amplifiers. The

output amplifier provides high current drive capability.

The digital data is sent via SPI interface, and cascaded

connections can be used. The SGM5348-12 provides

daisy-chain capability, which can update multiple

SGM5348-12s simultaneously by using a single serial

interface.

● Low Power Consumption (0.5mW/CH)

● Integrating 8 Channels of 12-Bit DAC

● Built-In Rail-to-Rail Output Amplifier:

Sink/Source Current with Short Current Control

● Daisy-Chain Operation

● 8 Channels Outputs Update Simultaneously

● Independent Channel Power-Down Function

 0.6μA (TYP) I_CCfor Power-Down Mode

● 0.1% (TYP) Gain Error for All Channels

● Interface Sees No Quiescent Current when V_BUS< V_CC

● Power-On Reset: Output Reset to GND

● Serial Data Input: Up to 40MHz Operation

● TTL Compatible Input Logic Level

The SGM5348-12 has two references (one reference

input for channel 1 to channel 4, and the other

reference for channel 5 to channel 8). Each reference

voltage operates independently from a 0.5V to V_CC

supply, providing a dynamic range of output as broad

as possible. The SGM5348-12 contains a 16-bit shift

power-down condition and the register/output value of

the DAC channels. All 8 channels DAC outputs can be

updated simultaneously or separately.

● Power Supply Voltage Range: 2.8V to 5.5V

● Double Reference Voltages Range: 0.5V to V_CC

● -40℃ to +125℃ Operating Temperature Range

● Available in Green TSSOP-16 and TQFN-3×3-16L

Packages

The SGM5348-12 incorporates a power-on reset circuit

that ensures the DAC outputs power to 0V and remains

0V until a valid write occurs. The SGM5348-12

provides a power-down function that allows each DAC

to be separately powered with three different output

terminations. When all the DAC channels are powered

down, the current consumption of the device reduces to

less than 1.5μW at 3V and less than 3μW at 5V.

APPLICATIONS

Battery Powered Equipment

Selectable Voltage and Current Sources

ADC Voltage Reference

Sensor Power Supply Voltage

Audio Signal Volumes Control

The SGM5348-12 is available in Green TSSOP-16 and

TQFN-3×3-16L packages. It operates over the

extended industrial temperature range of -40℃ to

+125℃.
